- D. m=audio 0 RTP/AVP 4 0 8 18 15
正解：C
解説：
You could probably get thru the test just knowing the payload IDs for G.711u being 0 and G.729 being 18.
G.729 = 18
G.711u= 0
G.711a = 8
G.723 = 4
G.728 = 15

- C. Pattem= \+.777011496929810, CSS=Intl_CSS
- D. Pattern= \+.496929810, CSS=Unrestricted-CSS, PreDot, Prefix=777011
正解：B
解説：
B is incorrect since it doesn't state in the answer that the translation pattern will discard the
"Pre.Dot", which means the final pattern will have the "+" sign at the beginning which will not match the route pattern in the screenshot which doesn't have a "+" sign, however if we use the translation pattern in Answer D we will be able to achieve that since the "+" will be discarded and
777011 will be prefixed so the final pattern will be 777011496929810 == Match.
